Plastic gears are mostly used in the textile, food, and automotive industries due to their silent operation, corrosion resistance, and light and cheap advantages. Plastic gears are generally manufactured by injection molding or hobbing methods. The excess costs of the molds used to produce parts in injection molding and the problems of wastes that occur during production in hobbing lead companies to additive manufacturing, which is an alternative application. In the additive manufacturing method, the desired amount of product is produced without the problem of waste. In this study, the wear resistance of plastic spur gears produced by the Fused Deposition Modeling (FDM) method was determined theoretically. In order to determine the service life of gears, wear tests were carried out in the Forschungsstelle fur Zahnrader und Getriebebau (FZG) type test device at the same load and rotational speeds. polylactic acid (PLA), acrylonitrile butadiene styrene (ABS), and polyethylene terephthalate (PETG) thermoplastic polymer materials were used in the production of gears. When the gears rotate at the same load and rotational speeds, the most wear was observed in ABS, PLA, and PETG at the theoretically calculated wear depths. PETG is the most resistant material in terms of wear.
塑料齿轮因其运行安静、耐腐蚀以及轻便廉价等优点，大多应用于纺织、食品和汽车行业。塑料齿轮一般通过注塑成型或滚齿加工方法制造。注塑成型中用于生产零件的模具成本过高，以及滚齿加工生产过程中产生的废料问题，促使企业采用增材制造这种替代应用。在增材制造方法中，能生产出所需数量的产品而不存在废料问题。在本研究中，从理论上确定了通过熔融沉积建模（FDM）方法生产的塑料圆柱齿轮的耐磨性。为了确定齿轮的使用寿命，在 Forschungsstelle fur Zahnrader und Getriebebau（FZG）型试验装置中，在相同载荷和转速下进行了磨损试验。齿轮生产中使用了聚乳酸（PLA）、丙烯腈 - 丁二烯 - 苯乙烯（ABS）和聚对苯二甲酸乙二醇酯（PETG）热塑性聚合物材料。当齿轮在相同载荷和转速下旋转时，在理论计算的磨损深度处，ABS、PLA 和 PETG 中观察到的磨损最为严重。就磨损而言，PETG 是最具耐磨性的材料。
